Topic 2, ex 1

acceleration

QuestionAnswer
Velocity the rate at which an object changes its position (speed w/ direction aka change in speed or/and direction)
Acceleration Rate at which velocity changes If the change in velocity is positive, so is the acceleration. If the change in velocity is negative, so is the acceleration ACCELERATION IS A CHANGE!!!
when does acceleration exist? *change in velocity (speed OR direction changes) = acceleration exists
Newton’s second law of motion law of motion stating that the amount of force applied to an object is equal to the product of the object’s mass and its acceleration
Net force sum of all forces acting on an object, taking into account their strength and direction
speed formula? distance / time
distance formula? speed * time
time formula? distance / speed
mass formula? force / acceleration
acceleration formula? force / mass
force formula? mass * acceleration
acceleration formula (another way to do it)? change in velocity/change in time
Friction Opposite of the direction of the motion
Newton’s first law of motion a moving object that is not acted on by an unbalanced force will remain in motion Known as the Law of Inertia Ex. a seatbelt pushes you back from the force of the brakes, protecting you
inertia An object’s inertia is the tendency of an object to reject a change in its state of motion

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
